Application August 24,

9 Claims.

This invention relates to bottle topping, with reference more particularly to devices for rimming or applying closure lip attachments to the mouth ends of paper bottles or the like containers,

6 and constitutes a companion to the invention set forth in my co-pending application Serial No. 160,703, filed simultaneously herewith, covering a machine for forming tubular sheet-material (bottle) bodies, the mechanisms of the two cases being closely associated and cooperable, one with the other.

A primary object is to provide a suitable device or means for applying an improved closure-receiving mouth piece or throat ring to the top or neck end of a tubular container body, and more especially to a frusto-conical milk bottle, made of paper.'

Another primary object is to provide a device or means to perform the stated function in an improved manner and so as to produce an improved result, i..e. to assure an adequately strong affixture and to give a better closure facility to the tubular end of the bottle body.

An important aim in connection with the provi sion of such device or means is to adapt or render thesame adaptable to an automatic operation in sequence and synchronism with the automatic tubular body forming machine of the aforesaid co-pending application, so as to perform the stated function as a secondary step in the manufacture of paper milk. bottles or other liquid containers, this purpose of course requiring and contemplating an automatic feed of the mouth pieces or rings to be applied to the bottle bodies.

One of the important features of the invention is to provide for the automatic and immediate release of the bottle bodies from the device as soon as the mouth pieces or rings are properly applied and aflixed thereto.

The invention will be best understood by further description with reference to the accompanying drawings, wherein one practicable embodiment thereof is illustrated in a very simple and somewhat elementaryform.

Fig. 10 is an enlarged cut-away view of the upper part of the bottle body showing the mouth ring applied thereto in cross-section and illustrating the angular relation of the walls after release from the applying device; and

Fig. 11 is a plan view, partly fragmentated, showing an arrangement for the automatic feed of the tubular or bottle bodies from the forming machine of the aforementioned co-pending application to the mouth rimming means or device of the present application, in readied condition for the intended appliance, so as to carry out the production in a continuous operation.

In the illustrative embodiment (see Figs. 1 and 2), a pedestal 12 supports an annular table l3 rotatable on an axis shaft l4. Free rotation is assured advantageously by resting the table directly upon double pairs of rollers Iii-I5 and l6l6 trunnioned in the pedestal, the first or larger pair in this instance being located close to theperiphery under what may be referred to as the operating side of the table, and the other or smaller pair being located nearer to the center under the opposite side of the table. Said pedestal may be of any convenient or desired form, such as A-type trusses braced together as represented in the instant example.

Mounted upon said table is a plurality of rim applying devices, denoted, generally by X, in series arrangement circumferentially.

These devices each and correspondingly comprise (see Fig. 3) an arbor l'l fastened to the table, as by bolting shown at l8. At the base of the arbor an arcuate plate l9, opened toward the table periphery, provides a back stop serving to receive and center the tubular or bottle bodies accurately under the working head. A similar back stop and the arbor is formed with a lateral head 20 providmg a guide for the operating members;

Through the aforesaid head an operating plunger 2| vertically extends into connection with a movable block 22. Said block is solid or unitary and formed with a hollowed boss or neck portion 2?. fitting upwardly into a counter-recess 23 formed in the arbor head and'the lower end of said plunger extends partially into this boss or neck portion for the connection of the two parts. A cross-pin 24 locked in place through said neck portion and the end of the plunger in this instance serves to connect the two parts, with a certain amount of play therebetween in the manner of a swivel, but the connection might instead be accomplished by threaded engagement, or in some other manner as preferred.

Said block 22 is also formed with a recess 25 in its lower face, which is wide and deep enough to receive the upper end of the tubular or bottle bodies and provides a peripheral vertical wall 22 engageable around the upper end of said bodies.

Fitting movably in axial direction intosaid recess,

is acap-shaped plunger 26, having a stem 26 extending upwardly guidably through the block into the aforenamed' hollow neck portion 22 thereof and headed, as by flanging 26 to prevent the plunger movement downwardly or outwardly beyond a predetermined point so as to emerge entirely out of said recess. A cross-pin 21 moving in but locked against dislodgment between opposing longitudinal slots 28 in the aforesaid neck portion of the block works in opposite limited directions as against the head 26 of the plunger stem as a check to the plunger movement in a manner and for the special purpose to be later described. The arrangement is such that the plunger movemen'tin opposite directions is independently limited by the aforesaid stem heading" 26 and the body of the plunger, 1. e. its downward or outward movement is limited by said heading striking the bottom of the hollow neck portion of the block and its'upward or inward movement is limited by the upward or inner face of the plunger striking against the bottom of the recess 25 in said block.

The upper end of the aforementioned plunger 2| is connected by a link 29 to an operating lever 30, which is itself pivoted, as at 3|, to the top of the arbor H. A weight 32 on the short arm of said lever in this instance serves to counterbalance the weight of the longer arm thereof, so that it can be swung easily, or with a slight exertion, in either direction up and down.

In operation, a tubular or bottle body 33 of the series to be acted upon is positioned on the device under the operating parts just described, i. e. .it is placed within the arbor against the centering back-stops l9 and iilx with its top open end directly beneath the movable members in. the guide head 20 and its bottom end resting upon the table l3. Said body 33 in this instance comprises a frusto-conical paper tube or shell, formed in series duplication from blank sheets of the paper material on the machine of the aforenamed copending application Serial No. 160,703 and especially designed for use as milk bottles. The top end of this bottle body is coated with an adhesive, both interiorally and exteriorally, and, upon said end, a mouth or throat ring member 34 to be applied is placed before the said body is introduced or positioned into place as described. Said mouth or throat ring member 34 (see Figs. 6 and '7) comprises simply a paper annulus pressed out into groove or collar form fitting loosely over the peripheral edge of the bottle body in the manner of a rim.

'With the bottle body in position, with the mouth or throat ring placed on its top, as stated, the handle 30 is swung downward. This actuates or slides the plunger 2i to move the'block 22 down over the opposed top end of said bottle body, with its peripheral wall 22 surrounding said end, to the position shown in Fig. 8. Simultaneously, the cap-shaped plunger 26 brought thereby into obstructed contact with the mouth ring 34 on the body end, into which it partially fits, is moved relatively upward into the recess 25 of the block against the back wall of the same, a vent 36 being advantageously provided in the block to relieve air pressure and assure free movement. Thus said mouth ring is forced down upon the extremital edge of the bottle body between said cap-shaped plunger 26 and the surrounding peripheral wall 22 of the block. Inother words, the ring is lapped over said edge of the body, with outer and inner portions 34 and 34' respectively, thereof engaged between the surrounding block and plunger parts and with the edge of the bottle body between its said portions. The spacing between said plunger and surrounding block parts is such that the overlapping fold or three plies of material therebetween are squeeze-pressed together in a'vise-like manner, so that the coating of adhesive on the inner and outer sides of the bottle end will cause a tight union bind of the ring thereto, with a formative and strengthening effect. At the same time, a central flange-like portion 34 of the ring is drawn tensionally upward under and against the lower edge of the cap-shaped plunger 26 so as to be formed into an annular shoulder providing an annular ledge on the inner side of the bottle body. The squeezing action of the plunger and surrounding block parts are alone suflicient to give the ring this formation, in addition to binding it securely to the bottle end. The bind of the adhesive may be augmented, if desired, by corrugating or ribbing the end of the bottle body, both interiorally and exteriorally as indicated at 36 in Figs. 5 and 10.

It will be observed (see Fig. 8) that in the ring applying squeeze between the plunger and block parts, the top end of the bottle body is pressed or bent outward from its normal inclination or taper. That is, it is. flexed at obtuse angle to the rest of the body wall in a substantially yertical plane between the overlapping portions of the riming ring being applied thereto. This is caused by the vertical plane arrangement or surfacing of the squeezing parts, so that the ring is applied in a. straight downward direction with its aforesaid overlapping portions, and especially the inner portion 34 lying in a perfectly straight provide for the positive retention of a closing top (not shown) inserted thereinto against the flange or ledge portion 34.

Asthe cap-shaped plunger 26 is moved upwardly, upon downward movement of the block 22 over the ring topped bottle end, it engages by its stem 26 under the cross-pin 21 and pushes said pin upwardly between its slots in the hollow neck portion of said block. This it does freely inasmuch as said pin slides readily in said slots and tends normally to drop by gravity to the bottom of the same, so that no resistance to such movement is presented. Upon upward movement of said block, however, by upward swing of the lever 30, the said pin 21, which extends end-wise beyond said slots (see Fig. 4), is brought into engagement under the guide head of the arbor and is thereby arrested and withheld from further movement with the block. Thereupon it obstructs further movement also of the'plunger 24 with said block and forces said plunger relatively downward or outwardly of the recess 25 as the block continues its upward movement.

This causes the said plunger to expel and release the bottle body with its applied mouth ring after the applicative operation, which would otherwise be held between the two squeeze parts suiliciently tightly not to release or drop readily without such provision for the expulsion. Actually a hard pull upon the body would be necessary without this release provision, inasmuch as the squeezing action between the plunger and block parts is so tight and vise-like that the ringed body would be retained in place by friction and so fail to liberate the parts for a subsequent operation.

A bottle body placed under the operative action of this mouth piece applying or top rimming device is left in the grip of its squeeze parts until the adhesive has dried and set sufficiently to bind the ring member fast thereto. No great amount of time is required for the purpose and a very brief period will be sufllcient. The ring afiixture will be completely effected in the passage of the device through a single revolution of the operating table. Therefore, at any operating point of the table, one of the devices can be released for discharge or withdrawal of a finished bottle body, while a preceding device in the series is put into operation on a fresh bottle body.

In the illustrated organization, the devices are operated-by hand, i. e., they are fed, actuated into clamp and release positions, and discharged, all by the action of an operator. The table also is operated or rotated by hand, being advanced a step as each device of the series is brought into action upon a bottle body placed thereunder. This operation or manipulation may be performed from a station such as represented at the bottom of Fig. 1. At this station, a convenient means of apply ing the adhesive to the top end of the bottle body is advantageously provided, as for instance by the receptacle 3'! at one 'side of the table; This receptacle is shown to be supported by a bracket or brackets 38 fastened to the table pedestal. It-comprises simply a vessel or small vat in which liquid glue is maintained at a predetermined level indicated by dotted lines in Fig. 2. Over the top of the receptacle there is fastened a collar or sleeve 39 having its interior wall sloping downward upon a gradual taper, into which one of the bottle bodies 33 may be inse'rted inversely, with its tip end extending a certain distance therebeyond into the receptacle,

as indicated in Fig. 2. In the bottom of the receptacle, under the aforesaid collar or sleeve, there is provided a shallow cup member 40, carried upon an S-shaped arm 4!. Said arm is fixed to or integral with a bar or rod 42 guidably sliding in a suitable bushing or part of the receptacle wall. The bottom end of this bar or rod 42 is conected by a link 43 with one arm of a pivoted lever 44 also supported by'the table pedestal. The other arm of said lever is connected as by a chain or rod 45 to a foot treadle bar 46 (see (Figs. 1 and 2).

The said arrangement is such that when said treadle bar is depressed, the pivoted lever 44 is swung to move the bar or rod 42 upward, thereby lifting the s-shaped arm 4| so as to raise the cup member 40 upward under the end of the bottle body 33- invertedly extending into the receptacle. In rising, this cup member carries a shallow depth of glue into contact with the end of the bottle body and thereby coats the same to the depth necessary for the ring attachment. It is returned to position of course by gravity upon release of the pressure on the treadle bar, and a spring or springs 41 connected between the receptacle and rod 42 assists this return. Of course some other gluing means might be used with equal or better facility and result, that which is here shown being merely exemplary of a convenient means for the purpose.

Although the organization here shown is operated only by hand, it is intended in actual practice to automatically operate the same in synchronism with the bottle body forming machine of my aforesaid application Serial No. 160,703, and to automatically feed the bottle bodies successively, from said forming machine, to the operative action of the topping devices in their series sequence. This of course requires an automatic means of placing or dropping the mouth or throat ring members onto the tops of the bottle bodies as they are fed successively from the one machine to the other. An elementary arrangement and mechanism for carrying out this purpose is represented diagrammatically in El 11.

%n said figure, an interconnecting drive between the two machines is represented by the chain 48 running between sprockets 49 and 50 of said machines respectively. This drive is so ratioed that with each step rotation of the forming machine, the instant topping machine is also advance rotated one step or the distance between adjacent devices X. With each step rotation, a discharged or empty topping device is brought into a predetermined position to receive a fresh. bottle body for the mouth ring application. Upon each step rotation of the forming machine, a bottle body formed thereon is discharged from one of its form elements 5| by a withdrawing device, such as represented by the wipe-off band or bar 52.

The bottle bodies discharged from said machine are dropped or delivered initially, inversely or small end first, into a receiver 53, which in this instance constitutes also a gluing device somewhat similar to that shown by the parts 31, 39 and 40 in Fig. 2. That is, the top end of the bottle body is dipped into an adhesive for the necessary coating therewith, the said receiver 53 having an inverted frusto-conical center 53 through which the bottle end will extend into a body of liquid glue thereunder. The said bottle body is then next turned over, against and over a tilting edge E5 5, upon its intended base, into the secondary position indicated by A on a feedboard or guide 55 leading to the operating table of the instant machine.

This turnover to operating position is effectuated by a device represented by the swinging contact arms 56 actuated by the aforementioned chain 48, through block or lug members 51 carried thereon; by impact against lower swing-arm portions or tripping to an independently impelled action (not shown), so as to swing at the proper moment in the feed progression. In other words, the feed of the bottle bodies is synchronized with the operation of the two machines.

From the position A the bottle body is moved next, as by an endless driven push member 58, to the third position B under a device or mechanism for dropping the mouth rings 34 thereonto. Such a device is represented at 59 and, in dotted lines, also in Fig. 5. This includes a chute or hopper (not individually referenced) in which a number of the mouth pieces 34 are stacked one upon the other from a suitable feed source. At the bottom end of said chute or hopper, a double escape device, indicated by the opposed pairs of pawls 60 and 60' at .diflerent levels, is so arranged and actuated as to release and drop the lowermost ring of the stack while engaging and holding the one next above. In other words, the opposing pairs of pawls 60 and 60' are alternately operated to engage under the edges of the rings at their respective levels, that pair at the lower level releasing to drop the lowermost ring at the proper moment onto a bottle body brought thereunder. The timing of this mechanism is of course related to the feed progression so as to operate at the proper moment.

From the aforementioned position B, following the drop of a capping ring thereonto, the bottle body is next and finally moved to position in one of the devices X, arrested therebefore, for the action of applying the mouth ring to its end. This final movement, like the preceding one, may be eiTected by the endless push member .58 or by another similar member. In some cases it may be effected by the push of the next successive bottle body into the position 3, although this is not considered to be so desirable inasmuch as it may not always push the body sufilciently far to center properly within the arbor i! of the topping device. It will of course be understood that the mechanical arrangement for automatic feed; with gluing and mouth ring topping, of the bottle bodies from the forming machine to the topping machine of the instant invention may be varied and constructed in any number of different Ways. That which is here described is merely elementary and only diagrammatically shown, the purpose b'eing merely to illustrate how it may be done according to the intended purpose. In a combination arrangement of the two machines, the actuating elements may be very differently formed and quite difierently operated, although their elementary purpose and accomplishment will be the same. The chief aim is to feed the bottle bodies vfrom one machine to the other,

with the proper preparation for the mouth piece application in transit, thereby eliminating the necessity to prepare and feed them to the topping devices by hand.

A The handles of th devices X are swung down to the operative position by a cam (not shown) engaging thereover as they leave the point of bottle body reception for ring application. Similarly the said levers are swung upwardly again.

to release position by another cam (not shown) engaging'thereunder as they return to the point for reception of another bottle body. Upon the release the mouth applied or rimmed bottle bodies may be discharged from the table by an extractor or Withdrawing device (not shown) directing them into a guide trough or chute 6|. Said chute may conduct them either to a point of stacking one within another for convenient shipment, or to a subsequent machine for bottom attachment, forming a. third phase or stepin the production of'paper milk bottles, and constituting another invention, for which a co-pending application, filed simultaneously herewith, has been made as a division or continuation in part claim as new and desire to secure by Letters Patent of the United States is:
